HyperAtlas can handle additional layers of information that can be displayed over the maps. Currently (May 2011), only a layer showing the main cities has been tested and can currently be supported.

The expected format for this "cities" layer incorporation into the dataset to be built is a .csv file. This file is only composed of three fields, these fields are separated by a comma character:

The following listing provides an example of the main cities layer definition csv file that has been used for European datasets (EPSG 3035):
